CAMBRIDGE, Mass., Feb. 9 (UPI) --
Harvard University scientists say they've determined invasive plants could become more prevalent and destructive as climate change continues.
The scientists, led by Assistant Professor Charles Davis, said they analyzed more than 150 years of data and discovered non-native plants, especially invasive species, appear to thrive during times of climate change because they're better able to adjust the timing of annual activities, such as flowering and fruiting.
